Using this BLOX cat back exhaust is straightforward. First, make sure your Subaru WRX or STI is from 2015 - 2021. If you have a stock j pipe or downpipe, install the GrimmSpeed adapter before fitting the exhaust. During installation, handle the exhaust with care as it's made of stainless steel but can still get scratched. Once installed, you'll notice an increase in power and a nice exhaust sound. For maintenance, regularly check for any signs of cracks or leaks, especially around the welds. Clean the exhaust tips with a mild cleaner to keep them looking good. If you live in an area with harsh weather, it might be a good idea to give the exhaust a protective coating to prevent rust.
